BAG-WORMS ON ORANGE. 



149 



Agricultural Report for 1858. Its basket is spindle-shaped, that of 

 the female IS™'^ (^ inch), and that of the male 13'"'" (i inch) long. It is 

 covered with finely chopped bits of dry leaf, bark, "q 

 moss and other scraps, supplemented not unfre- 

 quently with the scales of Bark-lice. As an addi- 

 tional jn'otection, several small orange thorns are 

 often fastened to the outside of the case, with their 

 sharp tips projecting backwards and outwards. 

 The pupa case is dark mahogany-brown, and the 

 sutures between the joints are opaque, black, form- 

 ing on the female pupa three, and on the male pupa 

 four, very distinct rings. The male is a small, dark- 

 brown moth, measuring IG""" (-Ak- inch) across the fig. 67—Piata-.ceticut

extended wings. The lemale, as in the preceding 



Bag-worms, is wingless, and undergoes a development similar to that 



of Oiketicus. 



UNNAMED BAG- WORM. 



[Fig. 68.] 



A species of Bag- worm smaller than any of the preceding exists upon 

 Orange, and is not uncommon. Its cases are long, slender, and cylin- 

 drical, and covered with fragments of bark, straw, »S:c. ; many of these 

 are linear, and have projecting ends. The female case (Fig. 68a) is

15"'" (,% inch), and that of the male 12""" (-^fo inch) long. 'VUv pupa 

 of the female (Fig. OS, h) measures 8'"'" (1*,,% inch) in length. The male 

 pupa (Fig. 68, c ; d, end of pupa enlarged) is very minute, being only half 

 the size oi' the female. Both are slender, bluntly-rounded at the ends, 

 and of a light chestnut color. 



Tlii.s snuill si)ecies is allied to J'.sychc confedcratd, by the slender form 

 and liglit color of its pupa, as well as by the construction and cylindri- 

 cal shai)e of its case. In Platceceticus, on the other hand, the fusiform 

 shape and dark color of the case and pupa, indicate a closer relation- 

 sliij) to Oiketicus.* 



* The species of Bag-worms are more numerous than has been supposed, and sev- 

 eral iiudescribed species are coufuded iu collections with the few species hitherto 

 described.
